    Abstract: A fluid filter (10) includes a first batting (12) of high loft, non-woven, fibrous fluid-permeable material with a plurality of openings (14) formed through the thickness thereof across the length and width of the batting. A second layer (16) of high loft, non-woven, fluid-permeable fibrous batting is attached to the first layer (12) and extends across the entire length and width of the first layer (12). Preferably, the first and second layers are adhered together to form a single integral fluid filter (10). In the preferred form of the invention, the openings in the first batting have side walls (48) which are perpendicular to the upper surface (36) of the batting, such that fluid flow impacts on the upper surface of the batting, rather than directly impacting on the side walls.

    Abstract translation: 流体过滤器（10）包括具有穿过其整个长度和宽度的穿过其厚度形成的多个开口（14）的高倾斜，无纺布，纤维状流体可渗透材料的第一棉絮（12）。 第二层（16）的高顶，非织造，流体可渗透的纤维棉絮连接到第一层（12）并延伸横跨第一层（12）的整个长度和宽度。 优选地，第一层和第二层粘合在一起以形成单个整体式流体过滤器（10）。 在本发明的优选形式中，第一捶击中的开口具有垂直于棉絮的上表面（36）的侧壁（48），使得流体流动撞击殴打的上表面，而不是直接 影响侧壁。

    Abstract: The present invention relates to an oil filtration unit (1) for removal of solid contaminants from contaminated oil, the oil filtration unit (1) comprising a housing (2) which comprises a housing inlet (3) adapted to receive contaminated oil from the surroundings and to release the contaminated oil to an inner opening (4) of the housing (2) at a first pressure (p1) and a housing outlet (12) adapted to release filtered oil to the surroundings, and an oil filter (6) for filtering the contaminated oil, the oil filter (6) being arranged in the inner opening (4) of the housing (2) and comprising a filter inlet defined by an outer surface (7) of the oil filter (6), an inner filter volume (8) adapted to receive filtered oil at a second pressure (p2), where the second pressure (p2) is lower than the first pressure (p1), and a filter outlet inside the housing (2) providing fluid/liquid communication between the inner filter volume (8) and the housing outlet (12) in order to release the filtered oil from the inner filter volume (8), where the filter outlet comprises a hydraulic resistance providing a fluid/liquid flow restriction between the inner filter volume (8) and the housing outlet (12) in order to increase the second pressure (p2) inside the inner filter volume (8) and to release the filtered oil from the inner filter volume (8) to the housing outlet (12) at a third pressure (p3), where the third pressure (p3) is lower than the second pressure (p2).

    Abstract: A liquid ejecting head includes: a first-flow-path-member having a first-surface in which a first-opening is formed; a second-flow-path-member having a second-surface in which a second-opening is formed; and a filter member disposed between the first-surface and the second-surface, in which the second-opening is larger than the first-opening in plan view, the filter member has a first-region in which first holes are provided, and a second-region positioned around the first-region and in which second holes are provided in plan view, the first-region includes a filter region which partitions off the first-opening and the second-opening and through which liquid passes, the second-region is in contact with both the first-surface and the second-surface, and includes a first-fixed-region to which an adhesive adheres, and an area of each of the second-holes is larger than an area of each of the first-holes in plan view.

    Abstract: A filtration filter having a planar shape and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction and extends in a second direction along at least a first portion of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.

    Abstract: A filtration filter having a tubular shape, defining a first opening and a second opening facing the first opening, and including a filter base that defines a plurality of through holes arranged in a square grid array. The filter base includes a continuous portion having a first set of through holes of the plurality of through holes, and a non-continuous portion having a second set of through holes of the plurality of through holes. The continuous portion extends in a first direction from the first opening of the filtration filter toward the second opening and extends in a second direction along at least a first portion of a circumference of the filtration filter orthogonal to the first direction. The non-continuous portion has the second set of through holes shifted relative to the first set of through holes of the continuous portion and extends in the first direction.
